Anatomical model generation

A non-transitory computer-readable storage medium for use in conjunction with a computer system, the computer-readable storage medium having stored thereon instructions that, when executed by the computer system, cause the computer system to perform operations comprising:

• receiving a plurality of location signals indicative of locations of a medical device in an anatomic structure of a patient;
• forming a three-dimensional data structure representing locations visited by the medical device within the anatomic structure;
• receiving one or more anchor portions representing locations relative to the anatomic structure;
• generating a three-dimensional surface representation of the anatomic structure of the patient,
• wherein—
• generating the three-dimensional surface representation of the anatomic structure of the patient includes a volumetric smoothing,
• the three-dimensional surface representation of the anatomic structure of the patient is constrained to contain at least a portion of the three-dimensional data structure, and
• the three-dimensional surface representation of the anatomic structure of the patient is constrained to exclude at least one of the anchor portions;
• and
• displaying, on a graphical user interface, at least one of a two-dimensional projection of the three-dimensional data structure, the one or more anchor portions, and a two-dimensional projection of the three-dimensional surface representation.

A method, comprising:

• forming a three-dimensional data structure based, at least in part, on received locations of an engagement portion of a cardiac catheter within a cardiac cavity of a human patient;
• receiving one or more anchor portions representing locations relative to the cardiac cavity;
• generating a three-dimensional surface representation of the cardiac cavity of the patient, wherein the three-dimensional surface representation of the cardiac cavity of the patient is constrained to exclude at least one of the anchor portions;
• and
• displaying, on a graphical user interface, at least one of a two-dimensional projection of the three-dimensional data structure, the one or more anchor portions, and a two-dimensional projection of the generated three-dimensional surface representation.
